Series Of Experiments

In a series of experiments which simulated the inspection of sheet material and simple items, target uncertainty was found in several cases to have a significant effect on search times. The distributions of search times and the numerous occurrences of target position effects confirmed that search strategies were not entirely random. By recording eye-movements, subjects were found to employ very different search strategies which highlighted the problem encountered when attempting to infer search strategies based exclusively on search times.

The aim of this study was to analyze visual search strategies of baseball batters during the viewing period of the pitcher's motion. The 18 subjects were 9 experts and 9 novices. While subjects viewed a videotape which, from a right-handed batter's perspective, showed a pitcher throwing a series of 10 types of pitches, their eye movements were measured and analyzed. Novices moved their eyes faster than experts, and the distribution area of viewing points was also wider than that of the experts. The viewing duration of experts of the pitching arm was longer than those of novices during the last two pitching phases. These results indicate that experts set their visual pivot on the pitcher's elbow and used peripheral vision properties to evaluate the pitcher's motion and the ball trajectory.

INTRODUCTION: This study is conducted to observe the effects of cognitive load on the visual search and attention allocation strategies of pilots. Research on pilots’ visual search strategies can provide valuable information regarding attention distribution and transformation, as well as useful situation awareness (SA) predictions.METHODS: A total of 18 pilots performed flight tasks in a two-condition (high and low cognitive load) within-subject experiment to compare their flight performance and eye movement indicators. Eye movements were tracked during the flight mission by a portable eye-tracking device.RESULTS: Compared to the low cognitive load task, in the high cognitive load task, the subjects exhibited shorter average fixation times (M = 420.38, SD = 60.56), higher fixation frequencies (M = 2.27, SD = 0.30), and lower saccade frequencies (M = 2.7, SD = 0.31). Their flight performance was better during the low cognitive load task, as evidenced by the lower entropy (M = 0.11, SD = 0.03) of their eye movements. Analysis of fixation time percentages and fixation counts showed that the distribution of attention to each area of interest was adjusted dynamically over the course of the given task.DISCUSSION: Significant differences were observed in both fixation order and fixation frequency across the instrument array. When the cognitive load is high, the subjects used more efficient eye movement patterns and search strategies accompanying a higher level of SA.Lu T, Lou Z, Shao F, Li Y, You X.
